Heat-shrink tubing sourcing for overseas SMEs
China-based sourcing and supply coordination for wire-harness, connector and equipment teams. Send a specification, drawing or a few practical dimensions—we coordinate the model match, sample and quotation.
Product-family values are representative. Every quotation identifies the proposed manufacturer, part number, dimensions, available document scope, MOQ and lead time.
Application first
Manufacturer and part number identified
Documents checked when required
Commercial terms stated per quote
You do not need a complete drawing. Cable diameters, a photo, an existing part number or a short application description can be enough to begin.
Scroll-driven product principle
Follow the installation principle as you scroll. Actual recovery behavior, temperature and final dimensions depend on the exact quoted product.
Select an expanded diameter that passes over the largest component.
Heat evenly using the product-specific installation guidance.
Confirm complete recovery, fit and the required finished coverage.
01 / Product families
Choose the closest family, then confirm fit, temperature, packaging and mandatory evidence against the quoted manufacturing model.
A practical 2:1 tubing family for electrical insulation, cable organization, identification and light mechanical protection. The current commercial reference is not presented as flame-retardant; mandatory flame or compliance requirements are matched to a separately verified exact model.
A 3:1 dual-wall tubing family combining a polyolefin outer jacket with a heat-activated adhesive inner layer for insulation, strain relief and moisture-resistant sealing around suitable cable joints and terminations.
Quick comparison
Final values and document scope are confirmed per quotation.
| Product family | Construction | Ratio | Temperature | Size range | Typical direction |
|---|---|---|---|---|---|
| HS-SW2 | Single-wall polyolefin | 2:1 | −55°C to +125°C | Ø0.5–50 mm | Insulation, bundling, identification |
| HS-DW3 | Polyolefin + hot-melt adhesive | 3:1 | −45°C to +125°C | Ø2.4–125 mm | Joints, connectors, terminations |
02 / Applications
The right tubing starts with the part, environment and installation—not a catalog code alone.
Insulation, branch protection, bundling and strain relief.
Crimped joints, soldered splices, cable exits and backshell areas.
Control panels, appliances, machinery and electrical assemblies.
Tubing matched to the electrical, thermal and dimensional requirements.
03 / Authorized source media
Supplier-authorized footage from a current manufacturing source. It supports source review and product understanding; exact product and document scope still follow the quotation.
An internal flame-test demonstration is available for source review. It does not prove that the current commercial price line or every size and colour meets a stated flame rating, and it is not a substitute for model-specific documentation.
04 / Documentation
Tell us what your project must meet. We review the available technical and compliance information for the proposed manufacturer's model, size, color and formulation.
Add a required standard to your RFQReports may cover only an identified sample, material, size or color. UL recognition, flame performance, RoHS/REACH status and CE applicability are confirmed separately for the exact quoted model.
05 / How it works
A lean process for overseas SMEs testing a source, sample or new application.
Share the application, dimensions, quantity and required compliance documents.
We compare manufacturers' models and review the available technical information.
The proposal identifies the manufacturer, part number, document scope, MOQ and lead time.
After approval, we coordinate production, packaging and shipment preparation.
A China-based supply partner
SLEEVANTA evaluates manufacturing sources and coordinates product selection, supplier communication, samples, quotations, packaging and shipment preparation. Every formal proposal identifies the manufacturer, part number, available document scope and legal seller/exporter before an order is confirmed.
06 / Request for quotation
Fill the details once, then choose email, WhatsApp or copy the prepared RFQ into any channel you prefer.
07 / Common questions
Yes. The current benchmark starts from one roll per size and colour, and an approximately 1 m factory sample may be available for selected standard items within China. International courier, cut lengths and final order terms are confirmed for the exact item in the quotation.
SLEEVANTA is an independent China-based sourcing brand. We evaluate manufacturing sources for each RFQ and identify the proposed manufacturer, part number, available documents and legal seller/exporter before an order is confirmed.
Certification and test scope can vary by manufacturing source, construction, size, color and formulation. Name every mandatory requirement in the RFQ so it can be checked against the exact proposed model.
Application, largest and smallest part diameters, quantity, color, length, temperature, mandatory documents and ship-to country. A drawing or current part number is helpful but not required.
